Hi, I've been looking for a 916 to purchase for a while and found a couple which happen to have 50mm + termis which are just too loud for me to inflict on my neighbours. I would still love to get one of the bikes but no point if i cant use it without waking up the whole street.

How effective are baffles? I've heard that they can reduce noise by 50% and can be removed for those times that i am away from home.

I'm not keen on drilling into the cans to fit baffles but would rather do that than miss out on a bike I wanted for 18yrs :-)

they do reduce the sound levels, by how much is a depends upon the condition of the end cans and the design of the baffle. A figure of 50% is very hard to define, as a 1dB decrease is barely discernable by the human ear. baffles would normally reduce the sound level output by around 5dB. Seeing as the measurement for a 916 would be at 5000rpm, anthing below this RPM would be quieter too....therefore being realistic, cant you just ride quietley out of your road?

Many thanks for the replies - yep I'd be dribbling out onto the road and away but even on low revs I think I'd be waking up a fair few people with an open can.

I might just go for it anyway but would have been nice to have a way to neuter it when leaving early hours. I'll give a couple of firms who make baffles a call and see if anyone of them have any advice.
